BRAZING COMPOUND.

No Drawing.

To all whom it may concern:

Be it known that I, JAY DELL GE Bor'r, a citizen of theUnited States,residing at Onalaska, in the county-of Folk and State of Texas, haveinvented certain new and useful Improvements in Brazing Compounds; and'Ido declarethe following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to a new and useful composition of matter to beused for brazing band saws, silver and tinware and any other metalscapable of being brazed together.

My improved composition consists of the following ingredients combinedin the proportions st-ated, viz :.-pure muriatic acid, 8 oz.; zinc insuch quantities as will be dissolved by the acid, which is about four(4) ounces; pure rain water, one pint; sal ammoniac, 3 oz.; powderedrosin, 3 oz.; cochineal, 1- oz. These ingredients are thoroughly mixedby agitation and are then strained through absorbent cotton until allsediment is removed, making a liquid which is absolutely free from grit,dirt and all foreign matter.

In the above composition the muriatic acid is employed for removing thedirt from the metal. As the acid in its pure state is too strong for thepurpose intended, it is reduced by the addition of as much zinc as willbe dissolved without leaving a sedi- Specification of Letters Patent.

ment. The rain water is added until the proper strength of acid isobtained. The sal ammoniac being a chemical known to have adhesivequalities is then added together with the powdered rosin which also hasadhesive qualities. These ingredients in the proportions named form acombination of chemicals which will work together in harmony to form aflux when heat is applied to the metal to be brazed either by theapplication of a hot iron or by a blow torch. The cochineal is simplyemployed for coloring the compound.

My improved compound when used as directed will not carbonize the metalbut will leave the same virtually in its normal state. The compound willprevent the irons from sticking to the metal after cooling and willcause the solder to flow freely between the laps of the metal thusmaking a braze that will be lasting and strong.

I claim:

The herein described composition of matter for use in connection withbrazing metals consisting of pure muriatic acid, 8 oz.; zinc 4 oz.; purerain water 1 pint sal ammoniac 3 oz.; powdered rosin, 3 oz.; andcochineal 1 oz.; substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses. I JAY DELL GE BOTT. Witnesses C. W. JAMES,
